The Cometic MLS head gasket for GM LSX (4.150in bore, .044in thickness) is a multi-layer steel gasket using advanced AMP-coated and uncoated stainless steel layers. Embossed outer layers handle harsh sealing environments and varied surface finishes, while the uncoated stainless center shim accommodates thickness needs. The MLS design requires less clamp load and helps distribute sealing loads evenly.
